Random Fatigue dialog box

Option	Description
Name	Sets the name of the random fatigue durability object. The durability object name is displayed in the event dialog boxes.
Random Fatigue Settings
Random Event Duration	Sets the duration of the random event in seconds.
Method	Specifies the method used to compute the random event results.**Narrow Band (Miles)**Computes the expected value of damage and fatigue life for a model which is excited with a random narrow bandwidth noise that has one dominant resonance frequency. The results from the narrow-band analysis are more conservative than those from wide-band analysis.**Wide Band (Dirlik)**Computes the expected value of damage and fatigue life for a model which is excited with a random wide bandwidth noise. Wide-band analysis results generally correlate better with experiments.
Fatigue Life Output
Event Damage	Requests fatigue damage results at each element of free faces for the event.
Event Life	Requests fatigue life results at each element of free faces for the event. The results are expressed in cycles.
